on my00 i aint touched these , yet !!!
just wondered what that weight is of the standard flywheel is ?

i am considering getting a lightened 1 but bearing in mind ive alot of hill around here and do use the gearbox for slowing down i dont wanna go to light

also,if i change the flywheel, have i got to do the pulleys or is just an advantage ??
and if i do do them will i have to get the map re-re mapped . . eh ? lol

cheers in advance

Std flywheel is approx 11KG. I am using a 4.2KG flywheel and engine braking is better than with the oem flywheel!

Some people say that it is wise to fit lightened pulley's at the same time as the fw to keep the crankshaft more balanced but others say it doesn't matter. I have the lightened fw fitted but will be changing the pulley's very soon when I change my cam belt. You won't need a re-map after fitting the fw and pulleys.

i just done the cam-belt lol
not a massive job though is it ?
could be my next plan but i am thinking of selling it for a 99 sti RA or 02 sti ppp
that ive got my eyes on

Roger Clark motorsport do lightened pulleys. Also, don't worry a thing about lightening your flywheel. Hill-starts have nothing to do with the flywheel unless you don't know how to engage the clutch correctly. The flywheel acts as a damper against rapid speed-change. Hence it will resist if the car tries to stall (as it often does in badly executed hill-starts). The flipside of the coin is that it dampens down the responsiveness of the engine. ie. if you spike it, the needle will slowly rise, and slowly fall. A lighter flywheel is an excelent choice and one everyone should make as soon as their clutch is taken down. Also take into account that the weight per se of the flywheel is not relevant. It's the rotational innertia that is. Unfortunately they never state that on the packaging. To expalin my point, immagine a flywheel with a thick center and one with a really heavy rim. The one with more mass concentrated in the middle is a lot easier to get spinning. The lightweight pulleys are unlikely to give you such a pronounced effect as the flywheel, and they are a little on the expensive side. I'd expect to pay around 200 pounds for the full set.
